Cereinae

Cereinae is a subtribe of cacti in the tribe Cereeae, subfamily Cactoideae. It is one of the six subtribes into which the tribe Cereeae was divided in 2023, the others being the monotypic Aylosterinae, Gymnocalyciinae, and Uebelmanniinae, along with Rebutiinae and Trichocereinae.^[1]

Genera

14 genera were firmly included in subtribe Cereinae in a 2021 study.^[2] This included Stephanocereus, treated as a synonym of Arrojadoa by Plants of the World Online as of September 2023^[update].^[3] Espostoopsis was not included in the 2021 study, but was noted to have been placed in Cereinae in many previous studies, including that by Lendel in 2013.^[2][4] Serrulatocereus was also not included in the 2021 study. It may not be distinct from Cereus as molecular phylogenetic studies have placed it in that genus, a placement accepted by some sources.^[5] A 2023 molecular phylogenetic study found that Stetsonia, formerly placed in subtribe Rebutiinae, belonged in Cereinae.^[1]
